COMPOUND SAFE OR VAULT DOOR.

Specification of Letters Patent.

Patented July 11, 1911.

Application filed November 10, 1909. Serial No. 527,126.

To all whom it may concern:

Be it known that I, SAMUEL WV. FISH, a citizen of the United States, and a resident of Plainfield, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in Compound Safe or Vault Doors, of which the following is a specification.

This invention relates to compound doors, the object of the invention being to provide a reinforced door for safes or vaults so constructed that it is made up of a pair of doors rigidly connected so that it may be swung or rotated as a single structure.

The present invention is an improvement in part upon that shown and described in my co-pending application, Serial No. 492,869, filed April 29, 1909, and also upon the applications contemporaneously pending herewith, Serial No. 526386, filed Nov. 6, 1909, and Serial No. 527,125, filed Nov. 10, 1909.

One of the objects of the present improvement is the provision of a compound door made up of a pair of integral doors rigidly secured together in such a manner as to form a chamber or space between the two doors, thereby to permit the use of a straight spindle such as that shown and described in my contemporaneously pending application last referred to.

In the drawings accompanying and forming part of this specification, Figure 1 is a rear view, partly broken away and in sec tion, illustrating this improved compound door; Fig. 2 is a cross-sectional view there of; Fig. 3 is a cross-sectional view of the outer or front door; and Fig. 4 is a crosssectional view of the inner or rear door.

Similar characters of reference indicate corresponding parts throughout the figures of the drawings.

In my prior improvements the joint surface of the doors was formed in part by each door, but in the present instance the inner door is so made that the entire joint surface for engagement with the jamb of the safe or vault is carried by said inner door, the outer door being within the inner door. The inner door, designated in a general way by A, comprises a body 2 of any desired formation having a rearwardly extending flange 3 and a forwardly extending flange l, the two flanges forming a tapered or coneshaped joint surface 5 having, when the door is formed as a rotary door, which is the preferable practice, two sets of integral locking lugs 6 for engagement with the lugs of the jamb. The rearwardly extending flange 3 and forwardly extending flange 4 thus form a chamber at the rear and front of the door respectively, these chambers being separated by the body 2 of the door. .The rearwardly extending flange 3 is provided with bolt openings for the reception .of bolts which may be used for preventing the rotation of the door after it is locked in its closed position by the locking lugs.

Located within the forwardly extending flange l, and therefore within the front chamber of the rear door, is the front door, designated in a general way by B, also comprising a body 10 and a rearwardly extending flange 11, likewise forming a chamber at the rear of the front door. This front door is provided with locking lugs 12 adapted to cooperate with similarly formed lugs on the interior of the front flange of the rear door, whereby the front door and rear door are interlocked rigidly by a rotary movement of one relatively to the other, and when so united are rigidly secured together against movement independently one of the other by bolts which project through the front flange of the rear door and the rear flange of the front door, the bolt openings 13 being provided with soft metal inserts 14 to permit the proper machining thereof when the doors are made of unmachineable metal such as manganese steel. In practice the united structure may be supported by some suitable form of hinge on the body, this being usually a crane hinge. It will be observed that the front and rear door bodies are so spaced apart that a chamber is formed between them, so that if it is desired to use a straight spindle in the manner shown in my contemporaneously pending application hereinbefore referred to this can be placed in position before the froht door is united with the rear door, and thus avoid the necessity of using a tapered spindle. It will also be observed that the front door is entirely located within the rear door, so that the door that contacts with the jamb is made up in one casting and there is therefore no danger of one door getting out of alinement or adjustment one relatively to the other, as where it forms .a part of the joint contact surface. Of

course, it will be obvious that the organization shown could be reversed if desired and the front door he so formed as to receive within its flange the rear door. It will also be observed that the inner surface of the forwardly extending flange is tapered inwardly toward the body of the door, and that the contacting joint surface of the front door has a similar formation, whereby the doors will have a tight joint surface between them so that the front door may be ground to its seat in the usual manner of forming a metal. to metal tight fit.

In practice the bolts which secure the two doors against rotation may also be utilized to project into the jamb to lock the door in the jamb against rotation, and for this purpose they would, of course, be connected with a suitable automatic or bolt operating means such as usually provided for that purpose and which would be located within the chamber formed between the two doors, these bolts in their normal unlocking position projecting through the openings provided in the forwardly extending flange of the rear door and the rearvardly extending flange of the front door.

I claim as my invention:

1. A compound door, comprising a rear door and a front door, said rear door having a forwardly extending flange adapted to receive interiorly thereof the front door therein, and means for securely uniting the two doors together.

2. A compound door, comprising a rear door and a front door, said rear door having a forwardly extending flange adapted to receive substantially the entire front door therein, and means for securely uniting the two doors together, said doors having a chamber therebetween.

3. A compound door, comprising a rear door and a front door, said rear door having a forwardly extending flange adapted to receive the front door therein, and means for securely uniting the two doors together, said means comprising cooperating locking lugs carried by the doors.

4. A compound door, comprising a rear door and a front door, said rear door having a forwardly extending flange adapted to receive the front door therein, and means for securely uniting the two doors together, said means comprising cooperating locking lugs carried by the doors and said do ors having registering bolt openings for he reception of bolts.

5.
